i might be selling my car or fitting a rotary engine to it. so if any awesome person knows of a place that can sell and fit a rebuilt rotary into my 1976 mazda 121 please share also i live in new south wales australia.

Mike at Rotorsport - Ingleburn, used to race an RX5 street sedan, back in the day.His first RX5 was Phil Alexanders. Mike built the weber fed, extend port 13B for my RX5,and I helped him convert it from an auto to a manual.

Here's some pics of his RX5 race cars - mid 80s:

1st RX5

It certainly made the RX2,3 & 4 brigade stand up and pay attention, especially when it started beating them all at Amaroo and Oran Park.

Get the piston running. And leave it as it is. Over time it will be worth more as a genuine car than a converted rotary.For the cost of the conversion If your patient and wait you may be able to buy a genuine RX5 for around the cost of the conversion.It won't be perfect but will be genuine and you will need to look hard and be patient.
